PLUGIN IS NO LONGER SUPPORTED. A NEW ONE IS CURRENTLY IN DEVELOPMENT. AS OF 30/04/2021 THE PLUGIN DOES APPEAR TO STILL FUNCTION
NEW VERSION: https://gumroad.com/l/autodynamicbonesultra
This unity extension allows you to automaticially add dynamic bones on any humanoid model turning a 30 - 60 minute job into a 5 - 10 minute job with just a few clicks depending on the complexity of your model.
The Unity3D extension is still in EA and the price will go up once it is completed.
The plugin can now automatically setup your "VRC AVATAR DESCRIPTOR" ready for vrc upload. You will still need to add your own mesh with the lip sync shape keys but everything else will be setup including 4 basic gestures(Lewd,Shocked,Angry and Calm, It is important to note that these animations will only work on a MMD head.)
